My DSD screen is coming up inverted despite full reboots. Help!

Over the month I’ve had this machine it has done this several times but doing the full reboot (holding the blue button down) after several tries has fixed it before.

Now, no amount of rebooting is getting the screen right-side up again.


So after about the 15th full reboot attempt the screen righted itself.

I’m now dreading the next time this problem arises thinking maybe 30 reboot attempts will be required!
